Not being able to properly use your web browser is a bummer. If you use Firefox on Windows 10 and your web browser is currently not responding, follow the troubleshooting steps listed below. The steps from this tutorial should help you address all the errors and issues that can cause hangs or freezes on Firefox.

How to fix ‘Firefox not responding’ errors in Windows 10

Initiate a restart

The first thing to apply is a restart. If Firefox is not responding it means that something stopped its processes. And a restart might be the perfect solution for reinitiating everything. So, close Firefox (if the classic way isn’t working, close the program through Task Manager) and also restart your Windows 10 system. Finally, run Firefox and verify if everything works as it should now; if not, go to the next troubleshooting solution.

Update graphics card drivers

One reason why Firefox can run with issues is related to outdated drivers for the graphics card. So, you need to make sure that your Windows 10 system runs on the latest driver updates.

  1. Click on the Search icon – it’s located near the Windows start button.
  2. Type Device Manager and click on the same entry that will be displayed.device manager windows 10 Firefox is not responding
  3. From Device Manager expand the Display adapters option.update graphics card Firefox is not responding
  4. Right click on each entry and choose ‘update driver software’.
  5. Done.

Automatically update your drivers

Updating drivers is a necessary action, but an annoying and tedious process. We recommend TweakBit Driver updater tool (approved by Microsoft and Norton) that can do it automatically for you with just a few clicks.

This tool will help you to avoid permanent damage to your PC by downloading and installing the wrong driver versions. Here is a quick guide how to do it.

    1. Download and install TweakBit Driver Updater
    2. driver updater starting windowOnce installed, the program will start scanning your PC for outdated drivers automatically. Driver Updater will check your installed driver versions against its cloud database of the latest versions and recommend proper updates. All you need to do is wait for the scan to complete.tweakbit driver updater scanning
    3. Upon scan completion, you get a report on all problem drivers found on your PC. Review the list and see if you want to update each driver individually or all at once. To update one driver at a time, click the ‘Update driver’ link next to the driver name. Or simply click the ‘Update all’ button at the bottom to automatically install all recommended updates.

      Note: Some drivers need to be installed in multiple steps so you will have to hit the ‘Update’ button several times until all of its components are installed.

  6. In the end open Firefox and see if this helped you.
